ColumnStore did not start correctly when server is rebooted without executing shutdownsystem first

Build testing: 1.4.3-1 Azure build 20200220

When ColumnStore is up and running, I just issued 'reboot" to restart the VM. When reboot is finished, ColumnStore is in the following state:

running shutdownsystem before reboot does not cause this issue.

running shutdownsystem and startsystem would bring ColumnStore back to operational state.

Further testing indicates that the issue occurs only on the first "reboot without shutdownsystem" after installation. After the first reboot, running "reboot without shutdownsystem" again did not cause the issue.

1.2.5-1 does not have this issue
1.4.2-1 also has this issue
